UNITED STATES WILLIAM H. OOSPER, OF CHICAGO, ILLINOIS.

IMPROVEMENT lN WEATHER-STRIPS.

Specification formin part of Letters Patent No. 195,206, dated September 18, 1877 application filed September 9, 1876.

To all whom it may concern:

Beit known that I, WILLIAM H. GOSPER, of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Weather-Strips; and I do hereby declare that the following is such full, clear, and exact description thereof as will enable others skilled in the art to which my invention appertains to construct and use the same, reference being bad to the accompanying drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure l is an elevation of a window-frame with a part broken away to show the invention. Eig. 2 is a longitudinal vertical section with the sash removed. Figs. 3, 4, and 5 are detail views on a larger scale.

This invention relates to weather-strips for windows; and it consists in a parting-stop or head, having a groove and a rubber weatherstrip on one side corresponding to the height of the upper window-sash, and on its other side a like groove and strip corresponding to the height of the lower sash, said weatherstrips being united at the top of one and the bottom of the other by a cross-strip in a crossgroove at the meeting-rail, to protect the open space at the end thereof.

In the accompanying drawings, A design ates the window-frame; B, the upper sash, and B the lower sash. G is the parting-stop or bead, which is grooved longitudinally on one side at c and on the other side" at c. The groove 0 begins at the top of the parting-stop, and runs down as far as the meeting-rail; and the groove 0 begins on the opposite side of thc parting-stop (J, and runs down to the bottom thereof, these longitudinal grooves being connected by a cross-groove directly through the face of the parting-stop.

A weather-strip, D, of rubber is set into these grooves, so as to extend obliquely outward on each side to meet the window-sash, and straight out at right angles to the parting-stop in the cross-groove to meet the end of the meeting-rail. It thus constitutes three weather-strips-one protecting each sash, and one the open space at the end of the meetingrail.

What I claim as new is- In combination with a weather strip or strips,

a parting-stop on one side, in its upper part,

and on the other side in its lower part, and

provided with a cross-groove opposite the meeting-rail, substantially as and for the purpose specified.

WILLIAM H. OOSPER.
